Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output. The IL201/202/ 203 can be used to replace relays and transformers in many digital interface applications, as well as analog applications such as CRT modulation. 2 .300 (7.62) typ. .039 (1.00) Min. .130 (3.30) .150 (3.81) 4° typ. .018 (0.45) .022 (0.55) 18° typ. .020 (.051) min. .010 (.25) .014 (.35) .031 (0.80) .035 (0.90) .110 (2.79) .150 (3.81) .300 (7.62) .347 (8.82) .100 (2.54) typ.
